To all whom it may concern:

Be it known that I, EDWIN S; Ponrnn, a

of the city-of New. York, borough of Manhattan, in the county of New York, and State ofNew York, have invented a new and Improved Framing Device, of which the following is a full, clear, and exact description. This invention relates to improvements in iramingdevices, an object of the invention being to provide a framing device which is in the nature of a gage registering with the film at a point removed from the aperture of the projecting machine so as to permit a properfra-ming of the pictures without the necessity of looking through the aperture.

mule-projecting machines are in opera tion it is a dangerous matter for the operator to attempt to look through the aperture at the film because the light rays are apt to burn I him, and it is the purpose of my invention to provide a gage at a point removed from the-aperture and preferably registering with that portionof the film known as the lower loop, which is readily observable at all times,

so that the operator can see at a glance whether or not ,the pictures are properly framed and if they are not, can properly frame them without the necessity of looking through the aperture and avoiding the necessity of framing on the screen which is particularly undesirable in high class motion 1ts upper end by means of a securing depicture houses.

A further object is to provide a framing device which can be readily attached to projecting machines in common use and which will add materially, to the art of picture pro jection.

, With these and other objects in view thea type of proiecting machine known on the market as the Simplex machine, showing.

my invention thereon, the View being in perspective.

, Figure 2 is a view in longitudinal section through the projecting machine.

F1gure3 1s a view in transverse section on the line 33 of Figure 9,

plate 17 and the bar 21.

ing lens holder having the ordinary film trap 8 at the rear thereof and 4 is the aperture exposing the film 5 which is intermittently moved across the same as is commonin the "art. s

6 represents the intermittent sprocket and 7 the' framing lever-connected by suitable arms 8 and a link 9 with mechanism as shown at 10', for imparting a partial turning movement to the intermittent sprocket to properly-frame the picture or film in the aperture 4. This mechanism is common with machines of the type described and forms no part of the present invention except in that .it constitutes the film moving means for framing. A

10-represents the lower take-up sprocket and between the sprockets 6 and 10 the film forms the ordinary lower loop as indicated at 11, and this lower loop is accommodated in a housing 12 which constitutes a portion of a door 13, the latter hingedly connected at itslower end as shown at 14, and secured at vice 15. V I

The housing 12 is made at its upper forward portion with an openingl6 through which the lower loop 11 of film 5 can be seen and in sight or" this opening 16 my improved gage- 17 is located as will now be described,

Thegage 17, which is shownin perspective in Figure 6, comprises a plate having a laterally projecting pivot pin 18 at one end,

which is pivotally supported in a bearing bracket 19 on the projecting casing 1 so that the gage constitutes a part of the casing and does not interfere with the opening and closing of the door 13. At thefr'ee end of the plate 17 a pair of laterallyprojectingrods 20 are secured and support a crossbar 21 and 'a gage wire 22 is located. between the pair of rods 20 and is secured at its ends in the The rods 20 and also the edges of the housing 12 constituting the walls of the opening 16, are re ces sed so as to provide clearness across the face otthe film and only engage the edges of the film, and the wire 22 is so positioned as to be spaced slightly from the face 01 the film to prevent rubbing.

The gage 17 is made with a finger 23 having a screw threaded opening 24 therein and a set screw 25 projects through a slot 26 in the side of housing 12 and is screwed into the threaded opening 24. This screw 25 has an annular shoulder 27 which bears against the outer face of the housing and serves as a clampto clamp the pivotal adjustment. The slot 26 permits a sufiicient adjustment of the gage 17 and the gage wire 22 to compensate for any contraction of the film.

Theoperation is as follows: The training lever 7 is operated to cause a partial rotary movement of the intermittent sprocket 6 to move the film 5 across the aperture 4 until the picture is properly framed therein. The operator then looks through the opening 16 to see if the gage wire 22 exactly registers with the division line between the pictures. If it does not, he adjusts the gage 17 by-means of the set screw 25, first releasing the set screw, then imparting a pivotal movement to the gage, and then clamping the gage after the wire is in exact register with the line between the pictures. This movement of the gage, as above explained, is necessary on account of the contraction which takes place in the film. After the gage is once set, it

operator to again will indicate at all times the proper framing of the pictures. In other words, after the gage is set, it is never necessary for the lookthrough the aperture 4 to frame the picture. He merely looks through the opening 16 to see whether or not the wire 22 registers with the line be tween the pictures and when the pictures are not properly framed, he moves the lever 7 and looks through the opening 16, and hence, it is not necessary when a machine is equipped with my improved framing device for the operator to look through the aperture of the projecting machine and thus run the risk of burning himself for he can properly frame by looking through the opening 16 to see the location of the gage wire 22 relative to the film.

Various slight changes might be made in the general form and parts described without departing from the invention, and hence ll do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. The combination with a motion picture projecting machine, of a framing device located at a point removed from the film framing device gage 17 at the desired arrangement of the aperture of the projecting machine, means for adjusting the film longitudinally, and means for adjusting the framing device to register with the film.

2. The combination with a motion picture projecting machine and means for adjusting the film longitudinally, of an adjustable registering With located at a point removed from the aperture of the machine.

- 3. The combination with a motion picture projecting machine and means for adjusting the-film longitudinally, and meanstormoving a film across the aperture of the machine to frame the picture therein, of a framinggage located at apoint removed from the aperture and registering with the film, said machine having an opening therein exposing the film and the gage.

4. The combination with a motion picture projecting machine having therein, an intermittent sprocket below the film aperture, and a lower take-up sprocket whereby the film is looped between said sprockets, of a framing device registering with the lower loop portion of the film and exposed through an opening in the machine casing.
